Renting houses, I would say half the pet owning renters would result in some pet related damage. A rug replacement or scratched wall. Repairable but not expensive. Then there would be one in ten that could do a significant amount of damage. Pee being the biggest one. A rug replacement is free thousand dollars. Let cats pee everywhere and you can have costs exceeding 40,000 dollars.

There is no real easy way to know which renter you have.
